Not sure, but probably oxidation. At any rate, the loss goes up as it ages.

What exactly happens to the foam in the coax?
What are the indications when it goes bad?
I have some brand new RG-213 still on the reel that has been storage in my
garage for about 18 yrs. When I retired from the Coast Guard I intended to
use it right away. Instead I got stuck in a CC&R restricted home due to a
lay off in my second career. I did complete my second career and am now
fully retired at a QTH where I can put up a tower and antennas and wonder do
I risk using the reel of RG-213 I have stored all these years. It has been
in a dark corner of a garage, never getting too hot or cold, never getting
wet or even exposed to dampness. I am really tempted to use it but wonder
what the indications would be if it has degraded.
